The ability of gum kondagogu [Cochlospermum gossypium (L.) DC.], a natural carbohydrate biopolymer, was investigated for adsorptive removal of toxic metal ions Cd, Cu, Fe, Pb, Ni, Zn, Hg and total Cr present in industrial effluents. Various physico-chemical parameters, such as, pH, temperature, equilibrium contact time, % biosorption and adsorption capacity, were investigated. Metal biosorption...

BACKGROUND AND AIM: Hyposalivation can cause many difficulties for patients like opportunistic infections such as candidiasis, mouth sores, and dysphagia as well as reduced quality of life (QOL). Methods such as using sugar-free chewing gum are recommended to treat this complication. Mastic is a natural substance and since it has various properties in addition ...

difficulty in swallowing (dysphagia) is common among all age groups, especially in elderly and children. orally disintegrating tablets constitute an innovative dosage form that overcomes the problems of swallowing and provides a quicksetof action. the purpose of this study was to formulate and evaluate an orally disintegrating tablet (odt) containing captopril while using croscarmellose sodium,...

Solid dispersions have been widely used to enhance the solubility of poorly water soluble drugs. In this study, solid dispersions of valsartan (VAL) with natural polymers such as hupu gum (HG), guar gum (GG) and xanthan gum (XG) were prepared by kneading technique in the weight ratios of 1:1,1:2,1:3 and1:4.The prepared solid dispersions were investigated by X-ray diffraction, infrared spectrosc...

Introduction:Many different kinds of chewing gum can increase the flow of saliva, and they have been proven to have anti-bacterial effects as well. The aim of this study was to compare the effect of natural turpentine and synthetic sugar-free gums on dental plaque pH after a sucrose challenge. Methods: This randomized clinical trial was conducted on 15 subjects, who refrained from oral hygiene ...

Guar gum can be used to effectively improve stability and mobility of microscale zerovalent iron particles (MZVI) used in groundwater remediation. Guar gum is a food-grade, environment friendly natural polysaccharide, which is often used as thickening agent in a broad range of food, pharmaceutical and industrial applications. Guar gum solutions are non-Newtonian, shear thinning fluids, characte...

Accumulating evidence suggests that the androgen receptor (AR) may play an important role in the development and progression of prostate cancer. To find new, useful compounds that effectively may attenuate the function of AR in prostate cancer cells, the authors investigated the effect of gum mastic, a natural resin, on AR activity. An androgen-responsive prostate cancer cell line LNCaP was use...
